Quick answer: Catering for 400 guests at a South Asian wedding requires a minimum of 8–12 serving staff, two or more parallel buffet lines, a dedicated outdoor kitchen with multiple large cooking vessels, and a carefully timed service plan. The total catering budget for 400 guests typically ranges from £14,000 to £36,000 depending on quality tier and menu.
A 400-guest South Asian wedding is a significant catering operation. This is not simply a scaled-up version of a smaller event — the logistics, staffing, equipment, and timing all require careful planning specific to the scale.
This guide covers the practical requirements of catering at this scale, with particular focus on the South Asian wedding context.
Kitchen and Cooking Infrastructure
A 400-guest wedding requires industrial-scale cooking infrastructure:
- Multiple large degchis or cauldrons: Biryani for 400 is cooked in 40–50 litre vessels. Your caterer should have multiple large pots that can be staggered through the service
- Minimum 4–6 commercial gas burners: Running simultaneously for main dishes, gravy curries, and side dishes
- Refrigeration: Sufficient cold storage for marinated meat and pre-prepared ingredients — commercial catering fridges, not domestic
- Generator: 80–100 kVA minimum for a full outdoor catering setup at this scale, plus the event power
- Water bowser or mains connection: 1,500–2,000 litre minimum water storage
Staffing Requirements
| Role |
Number for 400 guests |
| Head chef | 1 |
| Kitchen assistants | 3–4 |
| Buffet serving staff | 8–10 |
| Drinks service | 2–3 |
| Chai station attendant | 1–2 |
| Clearing/washing up | 3–4 |
| Total catering staff | 18–24 |
Food Quantities for 400 Guests
Indicative quantities for a standard South Asian wedding buffet at 400 covers:
- Rice (biryani/pulao): 80–100 kg uncooked rice, producing approximately 200–250 kg cooked
- Meat (for curries and main dish): 120–160 kg total (chicken, lamb, beef according to menu)
- Daal: 25–30 kg dried lentils
- Naan/bread: 3–4 pieces per guest = 1,200–1,600 pieces
- Dessert: 2–3 pieces of mithai or one dessert portion per guest plus a contingency of 20%
- Soft drinks: 2–3 500ml bottles per guest = 800–1,200 bottles/cans
- Chai: Plan for multiple refills — 1.5 cups per guest minimum = 600 cups of chai
Planning tip: Always over-order on staples (rice, bread, soft drinks) and under-order on expensive proteins. If you run short of biryani it is a crisis; running short of one curry dish is manageable if another is available. Build the catering plan so that the rice dish is produced in sufficient quantity above all else.
Service Timing at Scale
Serving 400 guests from a buffet in a reasonable time requires careful planning:
- Open two parallel buffet lines simultaneously — this halves service time
- Stagger table release if possible — not all 400 guests rushing the buffet at the same time
- Ensure replenishment is continuous — full chafing dishes at all times; never wait for a dish to empty before replenishing
- Bread supply is the usual bottleneck — if using live naan, deploy two tandoor chefs; if using pre-baked naan, have at least three dedicated warmers
Waste Management
A 400-guest South Asian wedding produces substantial food waste and packaging. Plan for:
- At least two large skips or 240-litre wheelie bins for food waste
- Recycling separation for cans and bottles
- Grease trap if any drainage is connected to the mains sewer
- Arrange waste collection for the day after the event — not a week later
Common mistake: Briefing the caterer on 400 guests but forgetting to account for the catering staff, venue staff, security, and other suppliers who also need to be fed. Provide a specific brief to your caterer for supplier meals — usually a simpler family-style service for 20–30 people in the kitchen area — and include it in the quote.
How long does it take to serve 400 guests at a South Asian wedding buffet?
With two parallel buffet lines operating efficiently, 400 guests can be served in 60–90 minutes. With a single line, expect 2–2.5 hours. At large South Asian weddings, the buffet often runs in informal waves as different family groups are seated, rather than as a single mass service — this is normal and reduces pressure on the queue.
How much does catering cost for 400 guests at an Asian wedding in the UK?
For a standard-quality buffet for 400 guests, budget £16,000–£26,000 for food and service in the Midlands or North of England. London and Home Counties pricing adds 15–20%. Adding live cooking stations and a premium menu can push the total to £30,000–£40,000 for 400 guests.
